Aspiration of foreign bodies into the airway is a common problem in spite of efforts to educate the public and it can be sometimes fatal accidents. A retrospective study has been performed for 34 cases of airway foreign bodies, which were obtained from April 1994 to August 1998 at Chunan hospital of Soonchunhyang University.

1) Among the 34 cases, 26 cases(76.4%) were under the age of 3. The ratio of male and female was 1.4:1.
2) The most common symptom after foreign body aspiration was intractable cough(38.2%).
3) Abnormal findings in the chest X-ray films were found 24 cases(70.6%) and the most common abnormal radiologic feature was combination of pneumonia and atelectasis(37.5%), followed by combination of pneumonia and emphysema(16.6%), pneumonia alone(16.6%).
4) The nature of foreign body was vegetables in 20 cases(58.8%), miscellaneous in 11 cases(32.4%), metals in 2 cases(5.9%) and plastics in 2 cases(5.9%).
5) By distribution of the location of foreign bodies, 26 cases(76.4%) were located in the main bronchus(20 cases in right side and 6 cases in left side), 5 cases were in trachea, 2 cases were in larynx and 1 case was located at carina level.
6) By duration of foreign body lodgement in the airway, 15 cases(44.1%) were found within 24 hours, 9 cases(26.5%) were within 7 days, 7 cases(20.6%) were within 30 days and 3 cases(8.8%) were found over 1 month.
